Frequently asked questions

What is the lug width of the Rolex Lady-Datejust 279178-0009?

The Rolex Lady-Datejust 279178-0009 has a lug width of 14mm. This measurement refers to the internal distance between the two lugs of the case and determines the exact strap width required for a proper fit. It is the standard lug width for all 28mm Lady-Datejust references.

What is the best strap for the Rolex Lady-Datejust 279178-0009 in yellow gold?

For an 18-carat yellow gold case such as that of the Lady-Datejust 279178-0009, an alligator belly strap with symmetrical grain in cognac, bordeaux or gloss black provides the finest balance between formal elegance and respect for the metal. Vegetable-tanned calfskin is a sound alternative for those who appreciate a developing patina over time.

How do you change the strap on a Rolex Lady-Datejust 279178-0009?

To replace the strap on the Lady-Datejust 279178-0009, the spring bars must be released from the case lugs using a dedicated fork-tip spring bar tool. It is advisable to work on a padded surface to avoid scratching the yellow gold case. Alternatively, Casati Milano offers strap fitting in the Milan atelier by appointment.

Are there aftermarket straps compatible with the Rolex Lady-Datejust 279178-0009?

Yes. Any strap with a 14mm lug width is geometrically compatible with the Lady-Datejust 279178-0009. Milano Straps offers a curated selection of handcrafted 14mm straps built to millimetre tolerance, available in alligator, calfskin, shell cordovan and rubber, with tang buckle or deployant clasp closure.

How long does a leather strap last on a Rolex Lady-Datejust 279178-0009?

Longevity depends on the material and daily use. A quality alligator strap, properly cared for and kept away from prolonged exposure to water and perspiration, typically lasts between three and five years. Vegetable-tanned calfskin has a comparable lifespan and develops a sought-after patina. Milano Straps products are covered by an 18-month warranty against manufacturing defects.
